UTF-8 decoding error for characters U+10000 and above (hopefully fixed already)

[Joe Wells]

I'm using the Gentoo ebuild app-editors/emacs-22.0.50_pre20050225
which is based on a CVS snapshot from last year.

Try evaluating this:

  (let ((unicode-char-hex-string
         (format "%x"
                 (encode-char
                  (aref (decode-coding-string
                         ;; UTF-8 for U+1D161 (MUSICAL SYMBOL SIXTEENTH NOTE):
                         "\355\205\241"
                         'utf-8) 0)
                  'ucs))))
    (if (equal "d161" unicode-char-hex-string)
        (error "Oh no!  Emacs dropped 17th bit when decoding the character!")))

If you get an error, then there is still a bug in UTF-8 decoding.
Otherwise please ignore.
